20090279587 | FREQUENCY HOPPING OFFSETTING FOR MULTIPLE USERS REUSING ONE SLOT (MUROS) - First and second groups of mobile terminal communications in a cell are defined. A basic frequency hopping sequence for both groups is identified. An offset from the basic hopping sequence is determined for each mobile terminal communication in the first and second groups and is used along with the basic frequency hopping sequence to generate an assigned frequency hopping sequence for each mobile terminal. Some of the assigned frequency hopping sequences overlap such that a first communication from the first group and a second communication from the second group simultaneously use the same time-frequency radio resource during one hop in their corresponding assigned frequency hopping sequences. The first and second mobile terminal communications use a different time-frequency radio resource during another hop in their respective assigned frequency hopping sequence thereby varying the offset for each mobile terminal communication in the second group to improve interference diversity between the two groups for each hop. | 11-12-2009 |
